Product Introduction
The Bently Nevada 16925-99 is a standard (non-armored) connection cable assembly used with the 177230 series vibration transmitter and 330400 series seismic sensor. It provides a shielded signal path between the vibration sensor/transmitter and the plant control system.
The 16925 series is the non-armored cable family for Bently Nevada vibration monitoring applications. The 177230 transmitter and 330400 sensor use a 3-pin MIL-C-5015 connector, and the 16925 cable assembly mates directly to this connector. The opposite end is terminated with terminal lugs for connection to a PLC, DCS, SCADA, or signal conditioning system.
The suffix “-99” identifies the cable length as 99 feet (approximately 30.2 meters), which is the maximum standard length in the 16925 family. This cable is commonly used on pumps, fans, compressors, motors, and other rotating equipment where the 177230 transmitter or 330400 sensor is installed for continuous vibration monitoring and the distance to the control system requires a longer cable run.

Quality Control Process (DYNAMIC GENERATION)
- Part-number verification: Confirm 16925-99 on the cable tag or packaging.
- Visual inspection: Check outer jacket for cuts, abrasion, crushing, or chemical damage along the full 99-foot length.
- Connector inspection: Verify the 3-pin MIL-C-5015 connector for bent pins, loose housing, or seal damage.
- Terminal end check: Inspect the terminal lug end for corrosion, loose crimps, or broken insulation.
- Continuity test: Verify 3-core continuity and shield integrity if test equipment is available.
- Compatibility check: Confirm the cable matches the 177230/330400 transmitter connector and the installed wiring configuration.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm this is a non-armored cable, not an armored cable. The armored version for 177230/330400 is the 16710 series. Substituting 16710 for 16925 provides more mechanical protection but may be unnecessary and more expensive. Conversely, substituting 16925 for a 16710 armored cable in harsh environments may reduce mechanical protection.
❗ Verify the -99 length code. The 16925 family uses different suffixes for different lengths (e.g., -10 = 10 ft, -33 = 33 ft, -99 = 99 ft). Using a shorter cable will not reach; a longer cable may create excess slack and routing issues.
❗ Check the connector type. The 177230 transmitter and 330400 sensor use a 3-pin MIL-C-5015 connector. Cables with different connector families will not mate correctly.
❗ Do not confuse with 3300 XL proximity probe cables. The 16925 series for 177230/330400 is not the same as extension cables used with 330100/330103/330105 proximity probes and 3300 XL proximitor systems (e.g., 330130 series).
❗ Maintain shield grounding. The shielded construction helps reduce electrical noise. Improper grounding at the system end can introduce signal interference.
❗ Inspect sealing components. If the cable assembly includes gaskets, seals, or strain relief hardware, verify they are intact to maintain environmental protection.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Alternative | Compatibility Level | Migration Notes |
|---|---|---|---|
| Bently Nevada 16925-99 | Same 16925-99 | Direct | Match length code (99 ft) and connector type. |
| Bently Nevada 16925-xx (other lengths) | 16925-99 | Needs Verification | Confirm required cable length and routing distance. |
| Bently Nevada 16710-99 | 16925-99 | Needs Verification | 16710 is armored; 16925 is non-armored. Same length, different mechanical protection. |
| 3300 XL proximity probe extension cables | 16925-99 | Not interchangeable | Probe extension cables are for eddy-current probe systems, not 177230/330400 transmitters. |
Benchmarks:
- 16925 series standard (non-armored) cable assembly for Bently Nevada 177230 / 330400.
- Length code 99: 99 ft (30.2 m), the maximum standard length in the series.
- 3-core shielded construction with 3-pin MIL-C-5015 connector.
- Used with PLC, DCS, SCADA, or signal conditioning systems.
- Third-party listings that describe 16925 as a proximity probe, proximitor, or monitor module are incorrect.
